Polyglot Desk — Privacy Policy

Effective date: 2026-05-08 · Last updated: 2026-05-08

This Privacy Policy explains how the Polyglot Desk browser extension ("the Extension") handles data on your behalf. The Extension is published by Legendary Feather, a Mexican individual with business activity (Persona Física con Actividad Empresarial). It is offered through the Chrome Web Store and other extension marketplaces.

This policy applies specifically to the Polyglot Desk browser extension. The Legendary Feather web application (legendaryfeather.com) is governed by its own Privacy Policy.

TL;DR. Polyglot Desk is a "Bring Your Own Keys" (BYOK) extension by default. Your API keys, settings, and saved phrases are stored only in your local browser. Audio you dictate and text you select are sent directly from your browser to the AI providers you choose (Ollama, Deepgram, Cartesia, ElevenLabs) — they do not pass through our servers. We do not run telemetry, analytics, or trackers in the Free tier. The Team tier (managed mode) is a separate offering and routes calls through our servers — see Section 7.

1. Data Controller

Legendary Feather, operating as a Persona Física con Actividad Empresarial registered in Mexico, is the controller of any personal data processed in connection with the Extension.

2. What the Extension Stores Locally

Everything below is stored only in chrome.storage.local on your device. It never leaves your browser unless you explicitly enable the Team (managed) tier. We have no access to it.

2.1 API keys you provide

Your API keys are your credentials — you obtain them from each provider directly, you pay each provider directly, and you can revoke them at any time. We never see them.

2.2 Your settings

2.3 Content you create

3. What the Extension Sends to Third Parties (and Where)

When you trigger a feature, the Extension makes a direct HTTPS request from your browser to the provider whose service powers that feature. Your data does not pass through Legendary Feather servers in the Free (BYOK) tier.

Each provider has its own privacy policy and data-handling terms:

4. What the Extension Does NOT Do

5. Permissions Explained

The Extension requests the following Chrome permissions. Each one is needed for a specific feature and is used only for that feature:

6. Microphone Access

When you activate voice dictation, the Extension requests microphone access via the browser's standard getUserMedia() prompt. The mic is active only while you hold the dictation hotkey. Audio is streamed in real time to Deepgram (your account) and never stored locally or remotely by the Extension. Releasing the hotkey terminates the WebSocket and the mic stream.

7. The Team (Managed) Tier — Different Data Flow

If you upgrade to the Polyglot Desk Team tier (paid, optional), the Extension routes calls through Legendary Feather's backend (legendaryfeather.com) instead of calling Ollama/Cartesia/Deepgram directly. In that mode:

The Team tier is opt-in. Users on the Free (BYOK) tier never have data routed through our servers.

8. Cookies and Trackers in the Extension

The Extension does not set cookies. The popup, content script, and detached window store data exclusively in chrome.storage.local, which is sandboxed to the Extension itself and inaccessible to web pages.

9. Data Retention

Because the Extension stores data locally:

10. Children

The Extension is not intended for users under 16. We do not knowingly collect personal data from children under 16.

11. Your Rights

If you've never paired the Extension with a Team account, we have no data about you on our servers — there's nothing to access, correct, port, or delete. If you did pair it, your rights are described in the main Legendary Feather Privacy Policy: access, rectification, erasure, portability, restriction, objection, and complaint to your local supervisory authority.

12. Security

13. International Transfers

By using the Extension you direct it to make HTTPS calls to the providers you choose, which may operate servers in the United States and other countries. Because the data flow is direct from your browser to those providers, the international transfer happens between you and them — not through Legendary Feather. Each provider lists its own data residency in their privacy policy.

14. Changes to This Policy

We will update this policy when the Extension's data handling changes (new third-party provider, new optional feature, new tier). Material changes are announced in the Extension's release notes on the Chrome Web Store and via a notification in the popup the first time you open the new version.
